No Cap in Started Franchise:
To turn off the cap in a franchise you already have started get your team extremely close to the salary cap (100k to 0k works for me) but you have to be missing a player you need (ex. have only 4 WR) then try to go to a regular or pre-season game it will say something to the effect of "You need a WR" then give you a choice to sign one or have the CPU sign it, choose CPU. Then it will pause for a second and say "no cap room choose cancel to sign player yourself or choose ok to turn off salary cap permanently. "Its that simple warning though this will turn off owner mode for good

Do you have a low salary?:
If you have a low salary and need to sign in new players don't turn your salary cap off. Because if you do you won't get Owner Mode.One thing you can do is that the computer automatically puts what the player want's in other mode how much money he wants lower it put the signing bones up. Somtimes the player will reject but keep on putting it up bye 10k and soon enough he will accept lower that what he was asking for.(while you put salary up little bye little put signing bones to it's max they like signing bones to it's max)

Bargain Basement Superstars (Franchise Mode):
Create a player without increasing any of his attributes. You can even lower them a little more to make his price as low as possible. Sign him for 7 years for next to nothing, then go back into "create a player" and increase his attributes to whatever you want them to be without raising salary. You can even max them out, but how much fun would that be?
